Got a nistune comp going in my 31 and it'll be on the dyno later this week. Does any one know if it possible to give it two separate tunings and how hard it is to switch between? ie: can i tune it for high performance on one setting and max economy on another, and is it as simple as flicking a switch while i'm driving or when the car is off? or would i need a controller to plug in or my laptop? I'm sure this is covered somewhere, couldn't find it at a glance so can any one tell me or point me in the right direction? cheers.

IMO there's no need, the high load high rpm cells will be right for the high performance and the low load low rpm cells will be right for max economy. You choose what you get via the right foot!

If you wanted two different tunes you'd have to get the nistune software and a consult cable and install the tune each time you wanted to change.

Once you get your final tune I can probably help you on switching tunes.

The ECU can be setup with a security feature or a different tunes for different fuel etc.

Let me know what the part number is and I'll double check.

I can run up to 4 different tunes in the R31 ECU and most switchable on the fly.

Kind regards

im always putting 98octane fuel in it any nothing else. I work at a servo so it's never out of my way to get it. So i don't want different tunes for different fuels. Is it worthwhile trying to tune it for better economy or should i just drive with a lighter foot?

I think it largely depends on who has tuned it.

but still ends up back with the Drivers ability to control the foot as well !!

As you have stated, there is no need.

A good tune will be economic when you are light on the throttle and have the power when you boot it.

Running multiple tunes would suit running different fuels (as mentioned above) or in a dedicated track car where the team may want to switch between tunes for different tracks/setups.

Stick the the one tune, goodluck with it :D

If boost is held constant then the best performance tune and the best economy tune will be the same.

Down low you'll have as much timing and as lean as it can handle eg off boost and with O2 feedback, up high you'll spend 2% of the time there if it is daily driven so it doesn't really matter how it is tuned.

Ask nistune themselves who they recommend to tune it.

there is no point, it should be tuned for maximum economy and best power in the one tune. the only reason to have multiple tunes is fuel changes. Nistune cant run multiple maps.

cheers for all the replies fulla's. It makes it easier on me now. Just gotta make sure i take it easy now then.

Nick is busting out some pretty good tunes lately... As everyone else said there is no real difference between a good power/economy tune as the afr's are the same for both (or there abouts).

The best way would be to install a electronic boost controller with hi/low boost switch... low boost is eco mode, hi boost power mode.

Power= air + fuel. Less power used = less fuel used- so just don't drive so hard.

Or install a throttle stop... ha h ah ha.

Cheers

oops, i didn't mean the throttle stop. i meant how hard is it to put in the electronic boost controller. or how much would that cost?

It's probably one hours labour for Marty to install it. Electronic boost controllers start around $400.

I have a dual stage boost contoller in mine with 7psi & 17psi for the exact reason as you want but its not needed as everyone has said before me. tunes it as high as you can go with boost/economy and use your right foot as the tuner.

i learnt the hard way as my switch is alway set to high now...

      R32 GTR EV? The leaf of the Godzilla's!

      By Duncan · Posted

      I can't agree. If we hadn't all been brought up with the noise caused by the inefficiency of an ICE, no-one would actually ask for all that. An EV is like any other car, it just goes better.

      2 more things I have to work out Easy one first...can anyone describe how to pull the fuel pump and sender from a 33? I can feel there is some sort of mount and clips but don't have a manual and don't know the trick......if not I'll spend some quality time in the boot witha lighter tomorrow. Second question is harder.  He had changed the upper plenum to a plazmaman but clearly got to a point with the vacuum hoses where he said "f**k it, I'm going inside for a beer" and never came back to that job because it was a mess. Am I right to think that I need: 1. Pre throttle (16mm nipple on inlet) to AAC's main 20mm fitting as the main pre throttle feed 2. ACC has a second 13m outlet joined to that 20mm fitting which I think is the pre throttle air supply for the cold start valve? 3. Cold start valve's outlet fitting then goes to Plenum (to bypass throttle?) There is some adapter on the back of the ACC with 2 fittings (13mm and 10mm), do I run the 10mm through a 1 way valve to the Brake Booster (4) and the 13mm back to a 13mm nipple on the Plenum as the Idle control (5)? 6. Run a 6mm vacuum line from the Turbosmart BOV to the Plenum? 7. Run a 5mm vacuum line from the Fuel Pressure Reg to the Plenum? 8. Run a 5mm vacuum line from the Turbosmart Boost controller to the Plenum? (Wastegate already has a pre turbo pressure source running to the solenoid then the wastegate on the other side of the bay)  Any help appreciated, the GTR is quite different setup and while the Stagea also has FFP it is different again. (And no Dose, I'm not pissing it all off and putting a ethrottle on it....)

      OK, onto some questions to try and speed up the process a little. Does anyone know what core this Garret is? I know it is a high flowed standard turbo but nothing else about it. Tag says OK 0169J - 446179-5032 Same question for the injectors, I don't know what they flow and ideally can work it out before it hits the dyno, they are a mustard yellow side feed

      Quick side trip into the engine externals, alternator and PS were in place including tensioned belts, but the PS was dry (my guess is he had the steering rack reco-ed). Filled it up with Transmax Z but it will need more bleeding once the engine is running no doubt. BTW I've said before, I don't know what kind of soft animals you have in the city, but out here they breed the rats tough. I bet they were disappointed when they tasted synthetic ATF.... Coilpacks are Splitfires with a factory loom in reasonable condition. I didn't pull one put I bet the spark plugs are new as its a new engine

      Onto intake pressure test. I have a Raceworks (damn brand thieves!) pressure test adapter that lets you apply pressure through a standard tyre valve and comes with a pressure gauge.....I just blocked off the other end immediately before the throttle body. Applied 30psi....and the turbo intake immediately popped off with a bang. Sorted that but it was still leaking, turns out there is a pinhole leak at the BOV adapter that I'll have to find a local place to TIG up. I'm sure it makes SFA difference with such a small leak but I want it to be right. Everything else up to the throttle body was good. Also cleaned and oiled the KNX cone filter, and this is the AFM if anyone can identify it (car runs a PowerFC)
